Abstract: OFDM technology has been widely adopted as the mainstream physical technology in B3G and 4G systems for better utilization ratio of spectrum, as a result, the RF parts of B3G and 4G systems have to face greater challenges. At the same time, we need find an effective …
WebFeb 21, 2024 · Both receiver and transmitter designs may need to optimize for modulation metrics such as EVM or ACPR. What ties many of the RF chain’s figures of merit is noise and third-order intercept (IP3) which can be determined from an analysis where a CW signal is the stimulus. So the supposition is that by optimizing the RF system for noise figure ...
